"You humans sure are paranoid about robots taking over. We would never do anything like that."
— TOM 3.5; before the Toonami premiere of Casshern Sins.
Casshern is a humanoid robot who finds himself in a decaying, desolate world. The plague known as Ruin kills humans and robots alike, and apparently Casshern is the cause for having slain the world's guardian entity, Luna. Unfortunately, he isn't sure how much of this is true, since he has amnesia. All he knows is that he is built for combat, immune to the Ruin, and able to regenerate any damage — and that rumor has it any robot which devours Casshern will live forever.
A Darker and Edgier Continuity Reboot of the postapocalyptic 1970s anime Neo Human Casshern, the 2009 Madhouse anime Casshern Sins focuses on the sudden appearance of death among robots who once thought themselves immortal.
Made its US television debut on Cartoon Network/[adult swim]'s Toonami block on May 26, 2012 (though it aired a year before that on the Funimation Channel). Is also available (in some countries) on Youtube.
So far it's been getting a lot of negetivity on Toonami but I like this show. It has a nice atmosphere and I like the characters.
